6 Best ADSL Modem Routers in 2020 (Reviews and Guide)

The best gift from technology to your home has to be ADSL (Asymmetrical Digital Subscriber Line) if you live in an area with low-market cable TV penetration.

 If you struggle to access the best cable TV, ADSL or DSL is the next best alternative. It’s not only the biggest completion for leading cable TV networks but also affordable and occupies a niche place within the entire internet ecosystem.

Now, DSL doesn’t come close to the current market’s Gigabit-level speeds most users get to enjoy because its operation is based on typical copper phone lines. However, DSL’s mode of operation makes it the best option for people living in areas not covered by advanced broadband.

For the performance you look forward to, the modems work in tandem with routers, hence a one-step upgrade process.

Having lived in the countryside for a huge chunk of my life, and the fact that I still prefer spending time away from the city, I have had my share of troubles when it comes to finding the best DSL modem routers.

This review is my way of saving you from hours searching for what would be the best ADSL modem-router, while also saving you time otherwise spent searching for the best options. Keep reading to find out which modem-routers work best for ADSL.

Choosing the best ADSL Modem-Router

While we all have varying tastes and needs around internet connections, we all need the best of these devices to enjoy good internet connectivity and to stay on top of things around the world. But these combo sets aren’t made the same, and some might cost you a lot in the future, which is why you need to be particular about the features of the set and what it has to offer.

In this section, we look at the details of ADSL and DSL modem-router combo sets and what you need to do or look out for when purchasing the modem router combo.

First things first…

What is a DSL Modem Router Combo?

ADSL refers to the best technological feature when it comes to high-speed voice and video transmissions to hokes, via the common copper telephone wires. Also called DSL, this feature represents the biggest competition to cable modems, with the DSL and Cable systems compared to each other depending on bandwidth or the amount of data transferable via a network.

The DSL modem involves an analog internet signal transmission via telephone lines to your house. Once the signal is in your house, those analog signals are then converted into a digital signal understood by your devices. This conversion takes place via a process referred to as demodulation by the modem. You also need the modem for the modulation of signals from your computer to the internet (digital to analog conversion of signals). The router then cones in, and it connects to your modem and your devices like phones and computers either through wired Ethernet ports connections or wirelessly via WiFi.

Therefore, the DSL modem-router combo is the internet unit connecting telephone lines to the internet, with the built-in modem and the router allowing for simultaneous internet connections to multiple devices.

What to look for in an ADSL/ DSL Modem Router Combo?

  • High internet speeds support – For high internet speeds, you need a modem-router combo with the fastest internet gigabit plans.
  • Upgradeability – is the device future-proof or easily upgradeable to support future technologies and functions.
  • Technologies – some of the best features you need in a modem router combo set lie in advanced technological features. Look out for things like Beamforming, DOCSIS, QoS, bonding, along with any other features that boost the device’s performance.
  • Security protocols – You need to look out for a device designed to offer safe and secure connections at all times. Think of WEP, WPA, WPA2, and VPN, among others.

Finally, make sure that the setup and the top speeds offered by the router are adequate for your gaming, streaming, or browsing needs.


Can you make your DSL Faster?

Yes. With low internet speeds for the DSL system resulting from different factors, for example, router malfunction that causes overheating or overloading, you need to work on ways of reducing congestion by sending minimal data packets from many connected devices. Also, make sure that the combo set purchased has a ventilation system to prevent overheating. Doing these will increase DSL’s internet speeds.

Alternatively, you could upgrade your DSL infrastructure through the installation of ports splitters or a cats5 Ethernet cable.

How do I boost my DSL’s WiFi Signals?

You could either use powerline WiFi adaptors to amplify your wireless connections or change your wireless channel to curb congestion. You could invest in a more robust router or update the DSL infrastructure.

Do you need specific Routers for DSL connection?

No. You only need the best modem for effective demodulation. A router will only connect to the modem, amplifying internet supply to different devices.


If you still rely on ADSL connections, either because you need to save by working with the low-budget ISPs or because you are waiting for Fiber installation in your location, the ADSL modem router combos above would be great options for you. There are numerous options on the market, but the features of the combos above make them the best options on the market for you.
